ILLUMINATING APPLIANGE.

Application med october s1', 1919. serial No. $34,642.

To all whom t may concern.'

Be it known that l, WILLIAM A. Donar, a citizen of the United States,and a resident of the city of Newark, county of Licka ing, and State ofOhio, have invented certain new and useful improvements in IlluminatingAppliances, of which the following is a specification.

The object of my invention is the conm struction of an illuminatingappliance comprising a light transmitting globe consisting of an innerenvelope resting on a lower rin member and an outer envelope supported ypressure of the inner envelope and the w lower ring.

This application covers the supporting and fastening means referred toin the companion application filed this day as Serial No. 334,643 inwhich such means are shown 2o in connection with one form of the deviceshown in the companion application, which application refers to thelight directing features of the device rather than the supporting means.

at The figure is a side elevation with parts shown in section.

In the figure, 1 is a source of light, 2 is the inner envelope of lighttransmitting glass. This is formed with threadings 3 at the ao lower endadapted to thread into the cylinder ring 4 and lip 5 at the upper endadapted to hold an upper cap, 6. A base 14 supports the unit. This ring,base and cap are not necessarily of the form or size shown a but mayhave any formation as long as they are adapted for the use indicated,and hold the inner envelope positively. The outer envelope is made intwo sections and is held by pressure in the manner indicated. The t0lower outer section 7 thereof rests on a flange or rim 8 of thecylindrical ring 4. The upper rim 9 of this lower section 7 of the outerenvelope permits the lower lip 10 of the upper section 11 to rest on itand by means of et the shape and form of lip 10 a firm seat is obtainedfor the two parts. The under side of lip 5 of the interior envelopepresses on the upper rim of the upper section of the outer envelope.Gaskets 12 are placed be- @e tween members at the various points ofconmi tact to insure a firm footing. The upper cap 6 is provided with alock-nut 13 to hold the cap firmly in contact with the upper part of theupper section of the exterior'envelope.

The particular form, size and shape of prismatic enclosure is not anessential part of my invention as the feature which is claimed as novelin this application is the maintenance in firm position of the outerenvelope by pressure of the parts against the interior envelope andagainst each other.

The metal parts of the xture may take any form to cary out theprinciples of the device. B5

This means of attachment is particularly adapted for street lighting andkindred fields.

Having described my' invention what I claim is: 1. An illuminatingappliance comprising a base a ring resting thereon, an enclosing lighttransmitting globe and a cap therefor, the globe consisting of an innerenvelope resting on the ring and supporting the cap and an outerenvelope of two sections, a lower section resting on the ring and anupper section resting on the upper rim of the lower section.

2. An illuminating appliance Vcomprising so a base, a ring restingthereon, an enclosing light transmitting globe and a cap therefor, theglobe consisting of an inner envelope resting on the ring and supportingthe cap and an outer envelope of two secso tions, a lower sectionresting upon and supported by a ange on the ring and an upper sectionresting on the upper rim of the lower section.

3. An illuminating appliance comprising n0 a base, a ring restingthereon, an enclosing light transmitting globe and a cap therefor, theglobe consisting of an inner envelope with'the lower part threaded onthe ring and supporting the cap, and an outer ena velope of twosections, a lower section resting upon and supported by a flange'on thering and an upper section resting on the upper rim of the lower section.

' 4.; A lamp unit comprising a one piece l g i Y l 1,492,020

casing arranged at one end to fit a standard and having threads at theoppositerend and anv external ange between said'ends7 a lamp globesupported on said ange, a top resting 5 on said globe, and a refractorextending thrQugh said `top into the globe having a flange engaging saidtop and arranged to screw into said casing. and thereby secure the globeand top to the casing. v
